Preserving seasoning flavour profiles during the manufacturing of food-seasoning sheets

Abstract

A method and an installation are provided for preserving desired seasoning flavour profiles during the manufacturing of food-seasoning sheets. The method includes the steps of; laying a thin layer of adhesive on a base sheet; removing air from the adhesive prior to the step of laying; reducing free moisture from the adhesive during the step of laying, and depositing food-seasoning ingredients onto the thin layer of adhesive. The installation for manufacturing food-seasoning sheets includes an adhesive dispenser having a reservoir and a delivery slot communicating with the reservoir for dispensing adhesive. The dispenser has a heating element mounted thereto for heating the adhesive. The adhesive is made under a partial vacuum and it is conveyed to the dispenser in a partial vacuum.

What is claimed is: 
     
       1. In a manufacturing of a food-seasoning sheet comprising a base sheet, a layer of adhesive laid on said base sheet and food-seasoning ingredients bonded to said layer of adhesive, the method of preventing a dissolution of said food-seasoning ingredients into said adhesive, comprising the steps of:
 receiving a volume of said adhesive in a slot die; 
 heating said volume of said adhesive and removing air and free moisture from said volume of said adhesive; 
 laying a thin layer of said adhesive on said base sheet; and 
 depositing food-seasoning ingredients onto said layer of said adhesive. 
 
     
     
       2. The method as claimed in  claim 1 , wherein said step of removing air from said adhesive comprises the steps of:
 removing air from said adhesive during a making of said adhesive in a first location, and 
 pumping said adhesive to an adhesive dispenser in an air free environment to a second location different from said first location. 
 
     
     
       3. The method as claimed in  claim 1 , wherein said step of laying comprises the step of controlling a volume of said adhesive according to a speed of said base sheet when said adhesive is delivered to said base sheet. 
     
     
       4. The method as claimed in  claim 3 , further comprising the step of removing air from said adhesive and from said base sheet when said adhesive is delivered to said base sheet. 
     
     
       5. The method as claimed in  claim 4 , further including the step of periodically creating a partial vacuum in said slot die.
